IMPROVEMENT IN CREASING ATTACHMENTS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 96,343. dated November 2, 1869.

To all whom it may concern:

Beitknown that I, CHARLES PAGE, ot' Washin gton, in the District of Columbia, butat present temporarily residing at Boston, in the county of Suffolk and State of Massachusetts, have made a new and useful invention having reference to machinery for sewing; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure l is a top view, and Fig/2 a side elevation, of a sewing-machine containing my invention.' Fig. 3 is a vertical section ot' the two rollers, their journals, and carrier, to be hereinfter described, the section being taken in the line of the axis of each journal.

In the drawings,A denotes an ordinary chainstitch sewing-machine, of which a denotes the needle, and b the base-plate. There is fixed to the said base-plate by means ot' a clampscrew, c, a roller-carrier, B, it having a slot, e, made through it to receive the clamp-screw and admit of the carrier being moved rectilinearly andadjnsted on the base-plate. The said carrier consists of a cylinder, j', or an approximation thereto, and a plate, g, extended from it in manner as represented. From one end ot' the said cylinder a journal, h, is projected, such being to receive the lower of a pair of rollers, C D. The spindle or journal h of the upper roller, D, is extended from a joint-piece, i, which rests in a recess in the upper part of the head f. At its outer end the said joint piece is hinged to the head, as shown at l, the whole being so as to enable the journal h', with the upper roller, D, to be raised away from the lower roller, as occasion may require, in order to admit the cloth to be sewed to be laid between the two rollers. The upper ofthe two rollers has a groove or crease, m, made in and around it to receive a corresponding creasing-rib, u, which is projected from and extends transversely around the lower roller. Each roller may be kept in place on its journal by meansot'a screw, o, projected from the journal, and also by a nut, p, screwed on the screw and against a washer, q, the whole being as represented in the drawings. The objects of these rollers are to keep the two br more layers of cloth in their proper relations to each other while being sewed together-that is, to keep either from puckering or gathering in folds on or under the other, as it is liable to do without the rollers; also, toV keep their edges in their normal or proper relations, and also to crease the two pieces where a tuck is to be madein each-such creasing being done by the creasing-rib and groove- While the pieces ot' cloth may be in the act ot' passing between the rollers for the purpose of being sewed together. The slot in the carrierplate serves to enable the creasing-rib and its groove to be adj usted at such distance from the middle or the line of the sewing as occasion may require.

I am aware of the cloth-creasing mechanism described in the United States Patent N o. 34,357, to W. L. Fish, wherein two narrow creasing-wheels are used-one being grooved on its periphery, and the other being made sharp or convex to enter such groove. I do not employ wheels, butcylindrical rollers, made so as not only to crease the cloth but to pre'- vent it while passing between them from becoming wrinkled or from puckering or gathering in folds, this latter function not being performed by the creasing-wheels of Fish, which are misnamed rollers.77 I make no claim, therefore,to the employment of creasin g-wheels made so as to crease the cloth only.

I claim as my invention the following, viz:

1. The combination of a sewing-machine, A,

and a pair of rollers, C D, composed of long cylinders arranged therewith substantially in the manner and for the purpose describedthat is, to operate to prevent the cloth while passing between them from becoming puckered or gathered.

2. The combination and arrangement 0i' the 'creasing-rib n and groove m with the pair of smoothing-cylinders C D and a sewing-machine, A, arranged together in manner and so as to operate substantially as described.

3. The arrangement and combination of the socketed roller-carrier B and the joint-piece t', hinged thereto, with the journals h h' and the rollers C D thereof, the whole constituting an apparatus or mechanism to be applied to a sewing-machine, for the purposes as set forth.

CHARLES PAGE.
